I don't have wireless like in that report but I do have two network
cards, eth0 for the host

and eth1 bridged for the guests.
So to try it I added NM_CONTROLLED=yes for eth0 and NM_CONTROLLED=no
for eth1 and br1, activated NetworkManager back and made sure that eth0 was
available to all users.

Booting Mandriva kept locking the host, so I created another mandriva
virtual machine
except this time I configured it as 'kernel 2.6.x', no virtio, and now
the host and the guests
